Body fertilizer can be absorbed and utilized by plant efficient.Comparative example 1 is that hydrolysis step does not use of the invention answer on the basis of embodiment 1
Acid is closed, but single nitric acid is used to carry out acidolysis, Liquid Fertilizer A ' is prepared；Comparative example 2 be on the basis of embodiment 2 not
Using Compound-acid of the invention and alkaline peroxide oxidation step, but only with single hydrochloric acidolysis, Liquid Fertilizer is obtained
B'；Comparative example 3 is not add alkaline peroxide oxidation step on the basis of embodiment 3, but only with Compound-acid acidolysis,
Obtain Liquid Fertilizer C '.Liquid Fertilizer A prepared by embodiment 1 and Liquid Fertilizer A ' prepared by comparative example 1 are applied in same crops kind
On eggplant；Liquid Fertilizer B prepared by embodiment 2 and Liquid Fertilizer B ' prepared by comparative example 2 are applied on same crops cucumber；It will be real
Liquid Fertilizer C ' prepared by the Liquid Fertilizer C and comparative example 3 for applying the preparation of example 3 is applied on same crops capsicum.Experimental result such as table
1。
Table 1
Note: the measurement method of organic matter liquid fat particles diameter is measured with particle diameter distribution instrument, instrument title: laser particle size point
Analyzer, model: Topsizer；Brand: American-European gram；The measuring method of ground object biomass (units increased in production): in the growth of crops
Phase root application Liquid Fertilizer A, B, C and A ', B ', C ', amount of application be 40kg/ mus, other planting conditions are identical, measure harvested production
Amount；
As seen from Table 1, the partial size for the Liquid Fertilizer A that prepared by embodiment 1 is smaller than Liquid Fertilizer A ' prepared by comparative example 1, thus
Find out that Compound-acid acidolysis effect is more preferable than single acid effect, and the partial size for storing 1 year later Liquid Fertilizer A is more stable, and Liquid Fertilizer
The partial size of A ' increased in 4500-6500, particle size, and from the point of view of the units increased in production of crop, Liquid Fertilizer A increases production than Liquid Fertilizer A '
Amount wants high, it can be seen that the smaller Liquid Fertilizer A of organic matter partial size is more favorable for plant growth；
Embodiment 2 prepare Liquid Fertilizer B partial size it is more much smaller than Liquid Fertilizer B ' prepare by comparative example 2, and storage 1 year with
The partial size of Liquid Fertilizer B is more stable afterwards, and the partial size of Liquid Fertilizer B ' has reached 6000-8000, it follows that using alkaline peroxidating
Organic matter after object oxidation acidolysis in liquid can make small molecule organic matter more stable, and partial size is made to maintain more conducively crop absorption
In the range of, and from the point of view of the units increased in production of crop, Liquid Fertilizer B is high than Liquid Fertilizer B ' units increased in production；
The Liquid Fertilizer C ' that the partial size of Liquid Fertilizer C prepared by embodiment 3 is prepared than comparative example 3 is compared, the partial size of Liquid Fertilizer C '
It is big compared with Liquid Fertilizer C, but partial size can remain unchanged substantially after storage 1 year, and this illustrates the small molecule that basic anhydride aoxidize
Organic matter is more stable, but is applied on Pepper crops, and the units increased in production of Liquid Fertilizer C ' is 8%, imitates not as good as the volume increase of Liquid Fertilizer C
Fruit, this illustrates that the small molecule organic matter after compound acidolysis is more conducive to crop and is absorbed and utilized, and promotes plant growth.
